Answer»

Answer:

The number was 723384.

Step-by-step explanation:

We have,

72a384 which is a number where 'a' is ONE of its digits, and it is divisible by 9.

Now,

We know that,

If a number is divisible by 9, its complete sum MUST be equal to 9

Here, adding the digits, we get,

7 + 2 + a + 3 + 8 + 4

= 9 + a + 11 + 4

= a + 24

Since a is a single digit, TAKING complete sum,

= a + 2 + 4

= a + 6

Now,

a + 6 should be equal to 9

So,

a + 6 = 9

a = 9 - 6

a = 3

So,

The number was 723384.

Hope it helped and believing you understood it....All the best
